Rodauth before 2.47.0 contains an authentication bypass vulnerability in the jwt_refresh route that issues new JWT access tokens without requiring a refresh token. Attackers can present an access token to the refresh route via non-POST methods to obtain a new valid access token, enabling indefinite account access with temporary token possession.
CVE-2026-82469
MEDIUMPre-NVD 5.45.4
EchelonGraph scoreLOW confidence
This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
